Cruise Control (Option)

This feature improves fuel mileage and reduces driver

fatigue by maintaining a constant vehicle speed. The

cruise control will only operate above a programmed min-

imum vehicle speed, 15 mph for the CAT 3126B engine,

30 mph for the Cummins ISC engine.

the minimum cruise control speed and the

engine speed is above 1100 rpm.

RESUME position at this point will select the pre-

viously set cruise speed.
